Science Fact: Women can find entirely different facial features attractive, depending on the kind of relationship they're looking for. Furthermore, they have a much broader definition of "attractive" than men do.

Explanation: Guys are pretty consistent when it comes to attraction. If you showed them pictures of women and asked them which ones they'd want to have romantic sexytimes with, they would furrow their brows, think super-hard, and be like "Ummmm... the hot ones." If you held up the same exact pictures and asked them which women they'd want to date, they would look at you blankly, like you were trying to trick them. "The... the hot ones," they would offer, confusedly. "QUESTION MARK?" they would think to themselves.

If you got a bunch of girls in the room to answer these questions, you would need spreadsheet software.
